DC and AC parameters
STCD22x0, STCD23x0, STCD24x0
This section summarizes the operating measurement conditions, and the DC and AC
characteristics of the device. The parameters in the DC and AC characteristics tables that
follow are derived from tests performed under the measurement conditions summarized in
Table 9. Designers should check that the operating conditions in their circuit match the
operating conditions when relying on the quoted parameters.
